Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing equipment technology, and in particular to a wrapping machine with an automatic correction mechanism. Background Technology

[0002] With the rapid development of intelligent manufacturing and industry, garment equipment is gradually moving towards automation and intelligence. Traditional sewing processes that rely on manual operation are being replaced by automated production equipment, which not only improves production efficiency but also significantly enhances the consistency of product quality. However, in the garment industry, the softness, deformability, and unstructured nature of clothing present numerous technical challenges for machinery in handling fabrics and accessories, especially in the areas of precise fabric feeding, positioning, and synchronous processing.

[0003] Taking the process of covering elastic bands on trouser waistbands or hems of clothing as an example, the traditional method usually relies on skilled workers to operate manually. The operator must hold a ring of fabric in one hand and an elastic band strip in the other, aligning and securing them, then sewing them together with a sewing machine to completely enclose the elastic band within the fabric, ultimately forming an elastic band structure with a gathered hem. This process is not only labor-intensive and time-consuming, but also demands extremely high skill levels from the operator, typically requiring highly trained and skilled workers. Due to the uncertainty of human factors, differences in operation between different workers often lead to inconsistent product quality, affecting yield and customer satisfaction.

[0004] To address these issues, automated elastic band wrapping equipment has emerged in the market in recent years, attempting to replace manual operation with mechanized automation to improve production efficiency and stabilize product quality. However, in practical applications, it has been found that the inherent unevenness, stretchability, and wrinkle-prone nature of fabrics make them prone to fabric shifting, wrinkling, and even tangling with the sewing needle during automated sewing, leading to poor stitching and a large number of defective or reworked products. This not only affects overall production efficiency but also increases production costs and wastes resources for enterprises. Utility Model Content

[0005] This invention overcomes the shortcomings of existing technologies and provides a binding machine with an automatic correction mechanism. It adopts a collaborative design of conveying correction components and auxiliary conveying components, enabling the fabric and elastic to rotate and be conveyed synchronously, avoiding offset or misalignment caused by speed differences. The rotating component drives the central transfer seat and elastic sleeve to rotate synchronously, ensuring that the fabric and elastic maintain a consistent motion state during the sewing process, improving product consistency and sewing accuracy. The annular air tube on the end cap blows air through multiple annularly distributed air holes, causing the fabric to form a "suspended state" with the end cap during the conveying process, greatly reducing the friction between the fabric and metal parts, preventing wear on the fabric surface and improving the smoothness of conveying, which is especially suitable for processing thin or fragile fabrics.

[0006] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution: A binding machine with an automatic correction mechanism includes a conveying adjustment device and an auxiliary conveying component disposed on both sides of a sewing machine.

Detailed Implementation

[0019] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0020] like Figures 1 to 16 As shown, a binding machine with an automatic correction mechanism is mainly used for the synchronous conveying and correction of fabric and elastic, and for completing the binding and sewing operation via a sewing machine. It includes a conveying adjustment device 2 and an auxiliary conveying assembly 3 located on both sides of the sewing machine 1. The conveying adjustment device 2 includes a conveying correction assembly A, which includes a rotating component A1. The rotating component A1 is used to engage with the auxiliary conveying assembly 3 and drive the fabric and elastic to rotate, thereby bringing the fabric and elastic into the sewing position of the sewing machine 1 for sewing. A rotating component A1 has a central pivot A12 at its end, which is connected to an end cap A16. The end cap A16 has an end cap groove A161, and an annular air pipe A17 is fitted into the end cap groove A161. The outer circumference of the annular air pipe A17 is flush with the outer surface of the central pivot A12. Several air holes are provided on the annular air pipe A17, arranged in a ring along the end of the rotating component A1. These air holes are used to blow open the fabric fitted onto the rotating component A1, allowing the fabric to move freely during the annular conveying process. During the process, the part of the fabric away from the elastic band can be blown up, so that the fabric at the end away from the elastic band will not be sucked back into the sewing position, ensuring the sewing effect. Moreover, during the fabric conveying process, the airflow blows the fabric up, making it "suspended" with the end cap surface, which greatly reduces the friction between the fabric and the metal parts, improves the smoothness of conveying and the integrity of the fabric. The outer circumference of the annular air tube A17 is flush with the outer circular surface of the transfer seat A12, making the fabric smoother when pushed into the transfer seat A12.

[0021] The auxiliary conveying assembly 3 includes an auxiliary moving module 301, which is connected to an auxiliary moving base 302. The auxiliary moving base 302 is connected to an auxiliary rotating motor 303. The auxiliary rotating motor 303 is connected to an auxiliary rotating shaft 305 via an auxiliary drive pulley set 304. Therefore, the distance between the auxiliary rotating shaft 305 and the sewing position of the sewing machine 1 can be adjusted by the auxiliary moving module 301, so that the equipment can adapt to elastic bands and fabrics of different sizes, thereby sewing trousers and other garments of different sizes.

[0022] The conveying and correction assembly A is responsible for the synchronous rotation and correction of the fabric and elastic band; the limiting assembly B is used to axially limit the elastic band and to flexibly adjust the limiting gap through the adjustment structure. The limiting assembly B includes a limiting ring B243, while the conveying and correction assembly A includes a rotating component A1, which includes a central pivot A12 and an elastic band sleeve A13; The transfer seat A12 is used to attach the fabric, and the elastic sleeve A13 is used to attach the elastic. One end of the elastic sleeve A13 is equipped with a fixed limit ring. When the conveying and correction component A is in operation, the transfer seat A12 rotates to drive the annular fabric to rotate synchronously, and the elastic sleeve A13 also rotates synchronously, thereby driving the elastic and the fabric to maintain a consistent motion state. The limiting ring B243 is coaxially disposed around the periphery of the elastic band sleeve A13. The elastic band sleeve A13 can reciprocate along the axial direction of the conveying and correcting assembly A through the driving action of the driving component B13. An axial gap is formed between the limiting ring B243 and the fixed limiting ring on the elastic band sleeve A13. The function of this axial gap is to limit the axial position of the elastic band on the elastic band sleeve A13. In this way, the operator can adjust the size of the axial gap according to the actual production needs to better limit the position of the elastic band in the sewing process, so that the elastic band can be controlled by the equipment during the sewing process, thereby ensuring the quality of the product. The adjustable size of the axial gap not only makes it easier for the elastic band to match the equipment, but also makes it convenient for the operator to adjust when changing styles, thus reducing the adjustment time of the equipment.

[0023] The limiting component B includes a width-limiting adjustment power unit B1, which is connected to an adjustment linkage component B2. The width-limiting adjustment power unit B1 includes a lead screw B11, with bearings B12 connected to both ends of the lead screw B11. The lead screw B11 is threadedly connected to a lead screw moving seat B12, which is connected to a linkage seat B16. The linkage seat B16 is slidably connected to a slide rail B14. The driving component B13 is connected to one end of the lead screw B11. The driving component B13 is a hand-cranked rotary table or a motor. Therefore, when adjusting the axial clearance, it is only necessary to rotate the lead screw B11 by cranking the hand-cranked rotary table or by directly driving the lead screw B11 with a motor according to the pre-set verticality. This will drive the lead screw moving seat B12 to move, thereby moving the adjustment linkage component B2. Finally, the limiting ring B243 on the adjustment linkage component B2 moves to adjust the axial clearance.

[0024] The adjusting linkage component B2 includes a linkage rod B21, with an auxiliary limiting slide seat B22 on the side of the linkage rod B21. The auxiliary limiting slide seat B22 is connected to a limiting stud B221. A limiting groove is provided on the linkage rod B21, and the limiting stud B221 is inserted into the limiting groove. The limiting stud B221 restricts the position of the linkage rod B21 in the lateral direction, so that the linkage rod B21 can only move along the coaxial direction with the lead screw B11. Therefore, it ensures that the relative position of the limiting ring B243 and the rotating component A1 remains constant, so that the limiting ring B243 will not collide with the outer peripheral structure of the rotating component A1 when it moves in the axial direction, thus ensuring the smooth sliding of the limiting ring B243.

[0025] The linkage rod B21 connects to the limiting component B24. The limiting component B24 includes a limiting base B241, which is connected to a diffusion extension seat B242. A limiting ring B243 is located at the end of the diffusion extension seat B242 away from the limiting base B241. The limiting ring B243 includes an inner ring B2431 and an outer ring B2431 arranged coaxially. The inner ring B2431 is used to directly contact the rubber band and restrict the axial movement of the rubber band during rotation. The outer ring B2431 is set to further limit the rubber band from slipping out. When the rubber band is stretched excessively and slips out from the edge of the inner ring B2431, the outer ring B2431 can further block the rubber band and prevent it from slipping to other places and affecting the operation of the equipment.

[0026] A first air blower seat B23 is provided on the side of the linkage rod B21 away from the limiting component B24, and the first air blower seat B23 is inserted into the first air blower tube B231. The air blower tube B231 ensures that the fabric is always wrapped under the elastic band before being fed into the sewing machine.

[0027] The limiting component B includes a blowing limiting component B3, which is located above the transfer seat A12 and on the side of the elastic sleeve A13 away from the transfer seat A12. The blowing limiting component B3 blows the fabric above the elastic sleeve A13, so that the fabric can pass over the elastic sleeve A13. After the fabric passes over the elastic band, it is blown downwards and away from the elastic band on the side away from the central pivot A12, so that the fabric can wrap around the elastic band. The air-blowing limiting component B3 includes an air-blowing linkage seat B31, which is connected to a rotating seat B32. The rotating seat B32 has a material flow limiting groove B33 on the side near the central rotating seat A12. A second air-blowing seat B34 extends from the rotating seat B32. The second air-blowing seat B34 has a second air-blowing pipe B35, a third air-blowing pipe B36, a fourth air-blowing pipe B37, and a fifth air-blowing pipe B38 arranged sequentially from the end furthest from the rotating seat B32. The second air-blowing pipe B35 blows the fabric over the end of the elastic band towards the underside of the elastic band. The third air-blowing pipe B36 blows the fabric from the central rotating seat A12 towards the elastic band sleeve A13. The fourth air-blowing pipe B37 blows the fabric and elastic band into the material flow limiting groove B33. The fifth air-blowing pipe B38 maintains the tendency of the fabric to wrap around the elastic band and be wrapped under the elastic band. Therefore, after the elastic band and fabric are connected to the rotating component A1, during the conveying process without rotating beyond A1, they are positioned by the air blowing limit component B3, so that the fabric can gradually wrap around one end of the elastic band during the rotation. Then, after being sewn by the sewing machine, the fabric and elastic band are fixed together. Therefore, it can be used for sewing processes such as elastic bands for trouser waistbands.

[0028] The rotating component A1 includes a rotating outer shaft A11 and a spindle A14 coaxially arranged with the rotating outer shaft A11; the spindle A14 is inserted into the center of the rotating outer shaft A11; the rotating outer shaft A11 is connected to the fixed middle seat A2 through a bearing, and the spindle A14 is connected to the rotating outer shaft A11 through a second bearing A143; the spindle A14 is connected to the first motor A4, the rotating outer shaft A11 is connected to the conveying component A3, and the conveying component A3 is connected to the second motor A5; the conveying component A3 includes a first synchronous pulley A31 and a second synchronous pulley A32, the first synchronous pulley A31 and the second synchronous pulley A32 are linked by a synchronous belt A33, the first synchronous pulley A31 is connected to the rotating outer shaft A11, and the second synchronous pulley A32 is connected to the second motor A5; the conveying component A3 is disposed in the central protective seat A6. Two motors control the rotation of the outer shaft A11 and the mandrel A14 respectively, allowing them to be controlled independently. The outer shaft A11 is used to transport the fabric for sewing, while the power of the mandrel A14 is mainly transmitted to the correction component A15. The correction component A15 is used to control the direction of the fabric perpendicular to the sewing direction, ensuring that one end of the fabric remains parallel to the elastic band during the sewing process. This ensures that the width of the fabric used to wrap the elastic band is consistent, thereby guaranteeing the stability of product quality.

[0029] The spindle A14 is equipped with a worm gear A141 and a first bearing A142; the first bearing A142 is connected to the central pivot A12, and the worm gear A141 is connected to the correction component A15; several correction components A15 are arranged in a ring and fitted into the central pivot A12, so no matter how the outer shaft A11 rotates, there will be correction components A15 in contact with the fabric, that is, the correction components A15 can correct the fabric throughout the entire sewing process between the fabric and the elastic.

[0030] In this embodiment, two sets of worm gears A141 are provided on the spindle A14, and several correction components A15 are divided into two groups. These two groups of correction components A15 are arranged with their heads and tails facing opposite directions and cross each other. The worm gears A1551 in the middle of the two groups of correction components A15 are respectively meshed with the two worm gears A141. The correction component A15 includes a first pulley A151 connected to the correction belt A156, a support wheel A152, a second pulley A153, a third pulley A154, and a worm gear structure A155. In this embodiment, the correction belt A156 is a rubber round belt.

[0031] The first outer peripheral section is the straightening belt A156 segment connected to the support wheel A152 and the third pulley A154. The first outer peripheral section is located on the outer periphery of the central pivot A12 and protrudes from the outer peripheral surface of the central pivot A12. The first pulley A151 and the support pulley A152 are connected by the correction belt A156 section, which is the second outer peripheral section. The second outer peripheral section is located on the outer periphery of the central pivot A12, near the end cover A16. The second outer peripheral section forms an obtuse angle with the first outer peripheral section; the second outer peripheral section is arranged at the outer end of the transfer seat A12. Since the two sets of correction components A15 are arranged in opposite directions and cross each other, it is beneficial to transport the fabric from the outer end of the transfer seat A12 to the middle of the transfer seat A12, and it is also beneficial to slide the fabric from the middle of the transfer seat A12 out of the end of the transfer seat A12.

[0032] The second pulley A153 is located inside the pivot A12 on the side close to the shaft core A14; the second pulley A153 pulls the straightening belt A156 away from the shaft core A14, so that the straightening belt A156 will not contact the shaft core A14, ensuring that the straightening belt A156 will not be worn, and also ensuring that the straightening belt A156 will not break due to wear.

[0033] The worm gear structure A155 includes a central worm gear A1551 and a side pulley A1552. The central worm gear A1551 is used to mesh with the worm A141; the side pulley A1552 is used to connect to the straightening belt A156.

[0034] In this embodiment, side pulleys A1552 are provided on both sides of the central worm gear A1551, and the first pulley A151, support pulley A152, second pulley A153, and third pulley A154 are all double pulley structures. Therefore, the correction component A15 can drive two correction belts A156 to rotate at the same time. The additional correction belts A156 make the correction effect more obvious.

[0035] A double-sided material feeding component D is also provided between the rotating component A1 and the sewing machine 1. The double-sided material feeding component D includes an upper material feeding surface D2 and a lower material feeding surface D1. The upper material feeding surface D2 is used to connect the upper part of the rotating component A1 and the sewing part of the sewing machine 1, and the lower material feeding surface D1 is used to connect the lower part of the rotating component A1 and the lower part of the sewing head of the sewing machine 1. A first limiting component E and a second limiting component F are provided between the upper material passing surface D2 and the lower material passing surface D1; The first limiting component E includes a first cylinder E1, the output end of the first cylinder E1 is connected to a first connecting rod E2, the first connecting rod E2 is slidably connected to a first limiting slide rail E3, the first connecting rod E2 is connected to a double-layer insert limiting seat E4, the double-layer insert limiting seat E4 extends from the side of the upper material feed surface D2 to the front end of the sewing part of the sewing machine 1; the end of the double-layer insert limiting seat E4 is provided with a limiting groove E41; during the sewing process, the lower layer of fabric and the elastic are inserted into the limiting groove E41, so that the lower layer of fabric and one side of the elastic are flush, thereby ensuring that the fabric just wraps around one side of the elastic after sewing.

[0036] The second limiting component F includes a first inner limiting group F1 and a second inner limiting group F2. The first inner limiting group F1 includes a limiting base F11. A second limiting slide rail F12 is provided on the limiting base F11. The second limiting slide rail F12 is connected to the lower end of the first inner limiting insert plate F14. The first inner limiting insert plate F14 is connected to the second cylinder F13. The second inner limit group F2 includes a third cylinder F21, which is connected to the second inner limit plate F23. The lower end of the second inner limit plate F23 is connected to the third limit slide rail F22, which is connected to the limit base F11. The first inner limiting plate F14 and the second inner limiting plate F23 can be inserted under the elastic band that has been wrapped in fabric but not sewn during the sewing process, so as to support the elastic band. Moreover, the ends of the first inner limiting plate F14 and the second inner limiting plate F23 also serve as the basis for the folding edge of the fabric to fold downward. Under the action of blowing air, the fabric folds downward along the ends of the first inner limiting plate F14 and the second inner limiting plate F23 to wrap the lower side of the elastic band. When the sewing of the fabric and elastic band is about to close a circle, the starting position of the sewing reaches the side of the first inner limit plate F14. The first inner limit plate F14 then retracts below the upper feed surface D2 to avoid obstructing the sewing. When the starting position of the sewing reaches the side of the second inner limit plate F23, the second inner limit plate F23 also retracts below the upper feed surface D2 to avoid obstructing the sewing. This ensures that the fabric and elastic band are supported during the sewing process, thereby ensuring the quality of the product. The sequential retraction of the first inner limit plate F14 and the second inner limit plate F23 also ensures that the fabric is not obstructed when sewing to the end, allowing the fabric and elastic band to complete a full circle of sewing. The double-sided feeding component D includes an upper feeding surface D2 and a lower feeding surface D1, and works in conjunction with the first limiting component E and the second limiting component F to ensure that the fabric maintains the correct orientation during the process of wrapping the elastic band, especially at the beginning and end of the sewing position to maintain stable support and prevent the fabric from sagging or misaligning.

[0037] A rib position detection component C is installed above the upper material feed surface D2. The rib position detection component C includes a detection lifting cylinder C1, the output end of which is connected to a detection elastic lever C2. The end of the detection elastic lever C2 is connected to a detection roller C21 and a detection insert C3. A detection sensor C4 is installed above the detection insert C3. When the fabric and elastic band are sewn into a circle, they need to be joined, and the joining point is called the rib position. During the process of the fabric wrapping the elastic band, the rib position becomes the location for determining the starting and ending points of the needle. Therefore, the location of the rib position is crucial to the sewing process. Since the rib position is more prominent than other fabrics, when the rib position passes under the detection roller C21, it will lift the detection roller C21, causing one end of the detection elastic lever C2 to pry up, thus allowing the detection insert C3 to insert into the detection position of the detection sensor C4, triggering the detection sensor C4. The detection sensor C4 is a metal sensor, thus transmitting the detection signal to the equipment.

[0038] The conveying and correction component A is connected above the base moving part H. The moving part H includes a base plate H1, a bottom slide rail H2 is provided on the base plate H1, the bottom slide rail H2 is connected to the bottom moving seat H5, a bottom moving limit block H3 is provided below the bottom moving seat H5, and a bottom limit pin H4 is also provided on the base plate H1. When the equipment needs to be repaired, the bottom limit pin H4 is pulled open. At this time, the bottom moving limit block H3 is not fixed, so the entire base moving part H can be moved, thereby driving all the components installed on the base moving part H to move together. After all the components are moved to the side away from the sewing machine 1, the front of the sewing machine 1 can be tilted to the side, so that the sewing machine can be repaired.

[0039] The bottom movable seat H5 is also equipped with a bottom side blowing component I, which is used to blow the fabric wrapped under the elastic band to the bottom of the elastic band. A correction detection component G is provided on the side of the conveying correction component A away from the sewing machine 1. The correction detection component G includes an adjustment handle G1 and an infrared sensor G2. In this embodiment, several infrared sensors G2 are provided. The infrared sensors G2 determine the position of the fabric wrapping around the rotating component A1 by detecting the edge position of the fabric, thereby calculating the width of the fabric wrapping the elastic band. The width of the fabric wrapping is then set according to the width of the elastic band, so that the appearance of the wrapped product is better after sewing.

[0040] During operation, based on production needs, the axial clearance between the limiting ring B243 and the fixed limiting ring is set by manually cranking the turntable or adjusting the screw B11 via a motor to accommodate elastic bands of different specifications. Next, the elastic band is fitted onto the elastic band sleeve A13 and the auxiliary rotating shaft 305, with the axial clearance of the limiting ring B243 restricting the position of the elastic band. Then, a ring-shaped piece of fabric is fitted onto the central rotating seat A12 and the auxiliary rotating shaft 305, with one end of the fabric extending near the elastic band sleeve A13, ready to wrap the elastic band.

[0041] Then, the second motor A5 drives the outer shaft A11 to rotate, and the fabric is rotated and conveyed. The first motor A4 drives the spindle A14, which is linked with the worm gear A141 and the worm wheel structure A155 to drive the correction belt A156 to rotate. The correction belt A156 continuously applies tension to the fabric through the obtuse angle distribution of the first and second outer peripheral sections to ensure that the edge of the fabric is parallel to the elastic band. Airflow is blown out of the pores of the annular air pipe A17, causing the end of the fabric away from the elastic band to be in a "suspended" state, avoiding adsorption or wrinkles; the third air pipe B36 blows the fabric from the transfer seat A12 to the elastic band sleeve A13, the second air pipe B35 blows the fabric over the elastic band and downwards to form a preliminary wrap; the fifth air pipe B38 maintains the trend of the fabric wrapping the elastic band to ensure a tight wrap; the fourth air pipe B37 blows the wrapped composite into the feed restriction groove B33 and stably conveys it to the sewing machine head. After the fabric wraps around the elastic band, the sewing machine head sews it together. The equipment first idles to locate the seams of the fabric and elastic band. Once the seams are located, sewing begins. The guide belt A156 continuously adjusts the fabric position throughout the sewing process to prevent misalignment. The limiting ring B243 restricts the elastic band displacement through axial clearance to ensure even stitching. As the seam is about to close, the first inner limiting plate F14 and the second inner limiting plate F23 automatically retract to prevent interference. After sewing, the finished fabric and elastic band are firmly bonded together, forming a stable binding structure. The finished product automatically detaches from the device, and a new batch of fabric and elastic band is fed in a cycle following the same process, allowing the equipment to run continuously.

[0042] This utility model of a wrapping machine with an automatic correction mechanism adopts a collaborative design of conveying correction component A and auxiliary conveying component 3. The fabric and elastic can be rotated and conveyed synchronously, avoiding deviation or misalignment caused by speed differences. The rotating component A1 drives the central transfer seat A12 and the elastic sleeve A13 to rotate synchronously, ensuring that the fabric and elastic maintain a consistent motion state during the sewing process, improving product consistency and sewing accuracy. The annular air pipe A17 on the end cap A16 blows air through multiple annularly distributed air holes, making the fabric "suspended" with the end cap during the conveying process, greatly reducing the friction between the fabric and the metal parts, preventing wear on the fabric surface and improving the smoothness of conveying, which is especially suitable for processing thin or fragile fabrics.

[0043] The limiting component B, through the structural design of the lead screw B11 and the linkage component B2, supports flexible adjustment of the axial clearance. The operator can quickly adjust the clearance between the limiting ring B243 and the elastic sleeve A13 according to different elastic band widths and fabric thicknesses, so as to realize the equipment's adaptability to various sizes of underwear and clothing, improving the equipment's versatility and changing efficiency.

[0044] The blower limiting component B3 is equipped with multiple blower tubes to blow the fabric in a directional manner from multiple angles, ensuring that it gradually wraps around the elastic band and maintains a stable shape during rotation. The first blower seat B23 and the bottom blower component I further assist in the positioning of the fabric, avoiding displacement or misalignment and ensuring the final sewing quality.

[0045] The mandrel A14 and the rotating outer shaft A11 are independently driven by the first motor A4 and the second motor A5, respectively, realizing separate control of fabric feeding and correction functions. The mandrel A14 is connected to the ring-shaped correction components A15 through the worm gear A141, ensuring that the correction belt applies correction force to the fabric regardless of its rotation angle, maintaining the parallelism between the fabric and the elastic band, and enhancing the consistency of the binding.

[0046] The bone position detection component C, in conjunction with the detection roller C21 and the detection sensor C4, accurately identifies the start and end positions of the fabric overlock stitch, ensuring the accuracy of the closed-loop stitching. The first and second inner limiting plates F14 and F23 retract sequentially before the stitching is completed to prevent the needle from being obstructed, ensuring the integrity of the stitching and the quality of the product's appearance.

[0047] The base moving component H and the limiting pin H4 design allow the equipment to be moved as a whole, facilitating the flipping and maintenance of the sewing machine head 1. The correction detection component G is equipped with an infrared sensor G2 and an adjustment handle G1, which detects the position of the fabric edge in real time and automatically adjusts the wrapping width, improving the intelligence level and ease of operation of the equipment.

[0048] The binding machine with an automatic correction mechanism integrates advanced technologies such as high-precision synchronous conveying, intelligent correction, pneumatic suspension, multi-stage air blowing limit, and modular structure. It boasts significant advantages such as strong adaptability, convenient operation, high degree of automation, and good product consistency. It is not only suitable for binding and sewing elastic waistbands in trousers, but can also be extended to other garment processing scenarios requiring simultaneous sewing of fabric and elastic materials, making it an indispensable key piece of equipment in modern intelligent garment manufacturing.
